You can simply disable default 10_linux script and use your own that
does whatever ordering you prefer. This is too specific for upstream
distribution. But it really seems like we need some additional layer on
top of raw grub script that allows manual reordering of entries among
others.

No, grub scripts do not require bash, so this is not going to work.
